pulsation damper mod
 

Hey all.. My PD screw is out.. I can't seem to find an 89-91 fuel rail.. How does this sound?

I've chopped the end off of the PD using a dremel cutting tool. Real easy to chop. The rubber diafragm was intact (for now)...but that's beside the point. What if I now tap and plug / braze / weld the end of it shut? I know, I know, hydraulic pulses and whatnot.. But, as a temp solution, at least. I imagine some braze or weld would plug it rather nicely...

If I recall correctly, you can just replace it with an M12 x 1.25 Banjo bolt. This would seem to be the safer alternative to hacking something out of the original part. Do this, or anything, at your own risk; I take no responsibility. :)

For what it's worth, I did an animation comparring the operation of the 84-88 and 89+ pulsation dampers. Check it out: Pulsation Damper Animation

Tesla,
You should be able to find another PD at Mazmart in Georgia or that salvage yard outfit in Rancho Cordova, CA. If all else fails, I've got a spare I was planning on holding onto, but I'll get it to you in lieu of you blowing yourself up with some of these homebrewed measures!
Blake! Great animation. Now I know what the do and what they look like inside!
